When I try to start up episode 3, must of the textures fail to load. Entire models are invisible. It makes the game unplayable. After loading up episode 3 and returning to the menu it is also corrupted. Strange thing is episodes 1 and 2 play just fine, the issues only arise with episode 3.
Running a Radeon 7970, latest WHQL drivers, everything is set to use the game's settings in the control panle.
